Stereoselective C-glycosylation reactions of ribose derivatives: Electronic effects of five-membered ring oxocarbenium ions
Larsen, Catharine H.,Ridgway, Brian H.,Shaw, Jared T.,Smith, Deborah M.,Woerpel
, p. 10879 - 10884 (2007/10/03)
The factors controlling the highly α-selective C-glycosylation of ribose derivatives were determined by examining the Stereoselective reactions of 18 ribose analogues differing in substitution at C-2, C-3, and C-4. The lowest energy conformers of the intermediate oxocarbenium ions display the C-3 alkoxy group in a pseudoaxial orientation to maximize electrostatic effects. To a lesser extent, the C-2 substituent prefers a pseudoequatorial position, and the alkyl group at C-4 has little influence on conformational preferences. In all cases, the product was formed by stereoelectronically preferred inside attack on the lowest energy conformer.
A new and efficient strategy for the synthesis of shimofuridin analogs: 2′-O-(4-O-stearoyl-α-L-fucopyranosyl)thymidine and -uridine

, p. 55 - 60 (2007/10/03)
Two shimofuridin analogs: 2′-O-(4-O-stearoyl-α-L-fucopyranosyl)thymidine (2) and -uridine (3) have been synthesized using D-arabinose, L-fucose, thymine, uracil, and stearoyl chloride as the starting materials. The synthetic procedures involve the facile preparation of 1-(3,5-di-O-benzyl-β-D-ribofuranosyl)thymine (9) and -uracil (10) by coupling of 1,2-anhydro-3,5-di-O-benzyl-α-D-ribofuranose (8) with silylated thymine and uracil, and then stereoselective formation of the 1,2-cis (α) interglycoside bonds through condensation of the nucleoside derivatives 9 and 10 with 2-(2,3-di-O-benzyl-4-O-stearoyl-β-L-fucopyranosylsulfonyl) pyrimidine (18). The 1,2-anhydro-3,5-di-O-benzyl-α-D-ribofuranose (8) was prepared by an improved procedure from D-arabinose.

Synthesis of 2'-O-[(4''-O-stearoyl)-α-L-fucopyranosyl]thymidine: A shimofuridin analogue
Ning, Jun,Kong, Fanzuo
, p. 2941 - 2944 (2007/10/03)
A synthesis of the title compound has been achieved. The procedure involves a facile preparation of 1'-(3',5'-di-O-benzyl-β-D-ribofuranosyl)-thymine (8) with 1,2-anhydroribofuranose (7) as the glycosyl donor, stereoselective formation of a 1,2-cis (α) interglycoside bond with 4-O-stearoylated pyrimidin-2-yl 1 thio-β-L-fucopyranoside (16) as the glycosyl donor.
